Add text props (lineHeight, letterSpacing, textCase, textDecoration, maxLines), spacing checks, update prompt
Renderer + export-jsx:
- lineHeight={N}, letterSpacing={N}
- textDecoration="underline"|"strikethrough"
- textCase="upper"|"lower"|"title"
- maxLines={N} (auto-enables truncation), truncate (standalone)
Describe:
- Spacing consistency checks (inconsistent padding/gap among siblings)
- Off-grid spacing values (not on 4px grid)
- Gap larger than padding warning
- Corner radius: child radius vs parent − padding rule
Prompt:
- Complete props reference with explicit "nothing else exists" guard
- Typography: type scale, line height, letter spacing, hierarchy rules
- Spacing: 4px grid, Gestalt proximity, consistency rule
- All new text props documented
Tests:
- 7 round-trip tests for new text props (render → SceneNode → export JSX)
